2960S-24TS-L - lanbase-routing

WAN-SOLO
Level 1
Level 1

Having troubles with all of my 2960S's with lanbase-routing enabled and 0 routed interfaces showing up in the template. I only have one SVI configured and that is the managment SVI 5

The current template is "lanbase-routing" template.

The selected template optimizes the resources in

the switch to support this level of features for

0 routed interfaces and 255 VLANs.

Other problems occuring are not being able to reach my neighbor, a 3750X and vise-versa. Both can see each other with a show cdp neigh det but can't ping each others managment IP. Not exactly sure what is going on because I can hook the 2960S up to an older 3750 and I'm able to reach the managment interface of the 2960S. Almost makes me believe that there is something going on the 3750X, but the 0 routed interfaces on the 2960S is somewhat troubling.

The 2960S is running IOS 15.0(2)SE and the 3750X is running IOS 15.0(1)SE3

I've changed some of the information in here for security purposes but wanted to give an output on what I'm seeing.

Othere strange happenings on other 2960S's is that when I do a sh cdp neigh det from my neighboring 3750X is that the management IP is showing up as the other SVI I have configured on the 2960S and not the SVI that I have setup for man

I have reached out to TAC on this but it has been hit and miss getting into touch with the assigned engineer so if anyone has a clue on this please let me know.

Thanks,

Dave

  Can you post the configs , hard to tell anything with just a show cdp neighbor.  I believe its all static routing on the 2960 so you will need statics on both sides of the links pointing back forth for anything that is configured on either box.  When you enabled routing on the 2960 did you reload the switch?  If you changed the template it must be reloaded to take effect.
